MACHENE FOR PLACING CROSS- WIRES IN SOLID RUBB ER TlRES SPECIFICATION forming part of Letters Patent No. 664,908, dated January 1, 1901.

Application filed January 6, 1900. $e1ial No, 622. (No model.)

To all whom, it may concern:

Be it known that 1, JAMES A. SWINEHART, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Machines for Placing Cross-Wires in Solid Rubber Tires, of which the following is a specification.

My invention has relation to improvements in mechanism for the manufacture of solid rubber vehicle-tires, and has especial relation to devices for putting cross wires or bars in the base of tires constructed in accordance with the invention described in United States Letters Patent No. 624,992, granted to me May 16, 1899.

The object of my invention is to feed for ward the tire before vulcanization by a stepby-step movement and to successively perforate the base of the tire, feed the wires or bars singly to the driving device, and insert them severally in the perforations by mechanism so constructed and arranged that the different parts shall simultaneously coact to effect these different steps.

To the aforesaid object my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically pointed out in the claims reference being had to the accompanying drawings, forming a part of this specification.

In the accompanying drawings, in which similar reference-n umerals indicate like parts in the difierent views, Figure 1 is a plan of the machine; Fig. 2, an elevation looking from the bottom of Fig. 1; Fig. 3, an elevation looking from the right of Fig. 1; Fig. 4, an enlarged view in section at the line so a; of Fig. 3, showing cross-wires resting in the hopper; Fig. 5, an enlarged view of the needleshaft, needle, and hammer intermediately broken to shorten the view; Fig. 6, a section of Fig. 5; Fig. 7, a plan, enlarged, of the needle shaft, needle, wire guide and connected parts, with a portion of a tire in sec tion to illustrate the operation; Fig. 8, a plan of the wire-guide detached, and Fig. 9 a section of the completed tire with the bar or wire inserted.

Referring to the figures, l is the table or base that supports the operative mechanism, resting on and across one end of which is a bar of wood 2, having a straight edge toward the mechanism and securely attached to the table. The tire 3 is placed on a movable board 4, having its upper face covered with canvas or duck to form a frictional contact with the tire, and this board is adapted to slide across the table against the bar 2, being held in place by a roller or small pulley 5, mounted on a stud on the table 1. In the bar 2 is firmly secured a short shaft 6, on which freely revolves a wheel 7 of such size as to rest against the tire as it passes, and thus form an abutment t0 the thrust of the needle, and with a groove in its face to prevent its encountering the point of the needle; On the top of the shaft 6 is adjustably mounted a horizontal wrist 8, bearing at its outer end a freely-running grooved pulley 9, having its groove of suitable configuration to fit the top of the tire. The edge of the board 4 opposite the bar 2 is provided at regular intervals with projecting pins 10, so located as to run above the roller 5. At the opposite end of the table 1 there is mounted in suitable bearings 11 11 a shaft 12, hearing at its outer end a balance-wheel 13 with a handle 14, so that it may be operated by hand, and between the bearings a pulley 15 to receive a belt, where it is desired to drive it by power from some other machinery. On the shaft 12 is an eccentric 16, from the strap of which a connecting-rod 17 extends and is provided with a pivotal bearing connecting it with a movable quadrant 18, pivotally connected with the table 1. ranged to move close to the ends of the pins 10 and bears a catch 19, arranged to pass the pins as it moves to the right in Fig. 1 and to engage one of said pins in its return stroke, thereby moving the board 4, with the tire thereon, a C nined distance to the left. This catch is s 'ld in engagement by a spring 39. On the inner end of the shaft 12 is a disk 20, hearing a wrist-pin 21, on which is pivotally connected one end of a connectingrod 22, the other end of which is attached to the needle-shaft 23. This connecting-rod 22 is intermediately coiled a single turn at 24 for a purpose to be stated. The needle-shaft The edge of this quadrant is ar- 23 slides in fixed guides 25 and has extending from-one side a thin plate or web 26, having at its outer end a round head 27, that constitutes the hammer to drive the wires into the tire, and in the top of the web a narrow groove 28, as shown in Figs. 4, 5, and 6.

Rigidly secured to the table by supports 29 30 is the wire-guide 31 adjacent to and parallel with the needle-shaft. This guide (shown in section in Fig. 4. and in elevation in Figs. 7 and 8) consists of a round bar deeply grooved longitudinally on one side to form a channeled course for the hammer 27 to move in and at the point 32 in Fig. 8 is beveled from below, so as to form a seat for the spout 32' of the hopper, hereinafter to be described. Directly above this seat and with sufficient space between to permit the wires 38 from the hopper to enter singly is secured a plate 33, the object of which is to prevent the wires 38 in their descent from the hopper getting outside of the groove in the guide 31. The lower edge of this plate fits in the groove 28 in the web 26, heretofore referred to. This plate 33 forms the top and the beveled portion of the hoppenframe 3st at the point 32 forms the bottom of a spout by which the wires are fed to the channeled course, hereinbefore referred to, in the wire-guide 31. The wires 38 to be forced into the tire being of proper size are placed in the hopper 34, fitted and arranged to turn in the bottom of which is a solid cylinder 35, having grooves in its periphery to receive single wires. This cylinder 35 is mounted on a shaft 36, on the outer end of which is a spur-wheel 37, arranged to have one of its points engaged by the coil in the connecting-rod 22 in its return stroke, and thereby given a partial rotation sufficient to permit one of the Wires to escape from the cylinder 35.

In operation a tire is placed on the cloth face of the board 4 and the latter passed into its path beside the bar 2 from the right of Fig. l and preferably pushed forward until the tire is in position to be engaged by the needle. Power is then applied to the machine, which feeds the board and tire progressively forward. At each rest the needle pierces the tire and at each succeeding rest a wire 38, released from the hopper, falls into the wireguide 31 and is driven into the hole last made by the needle by the hammer moving in unison with the needle as it makes the next puncture, thus placing these Wires with the utmost accuracy of distance and with great rapidity.
